Future Updates for CRM 4.0

Due to the low volume of fix requests for CRM 4.0, the CRM SE team will stop shipping CRM 4.0 rollups on a regular schedule. CRM SE will service CRM 4.0 requests on an individual basis using our Critical On-Demand process.

CRM SE will continue to evaluate the need for Update Rollups for the remainder of CRM 4.0’s supported lifecycle. A rollup will be shipped if there is a significant increase in fix request volume or in the event that a rollup will benefit a majority of the 4.0 installation base.

Note: In special cases, charges ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The usual support costswill apply to additional support questions and issues that do not qualify for the specific update in question.
